The works of Robert E. Howard included a multitude of horrifying creatures that Conan had to fight on his many journeys. In Horros of the Hyborian Age, GMs can bring those horros to the tabletops in their Conan RPGs. The pdf version of the book is available now.
From the website:
THOSE EYES GREW AND BECAME GIGANTIC, AND IN THEM THE CIMMERIAN GLIMPSED THE REALITY OF ALL THE ABYSMAL AND BLASPHEMOUS HORRORS THAT LURK IN THE OUTER DARKNESS OF FORMLESS VOIDS AND NIGHTED GULFS.
Horrors of the Hyborian Age is the definitive guide to the monstrous creatures inhabiting the dark tombs, ruined cities, forgotten grottos, dense jungles, and sinister forests of Conan’s world. This collection of beasts, monsters, undead, weird races, and mutants are ready to pit their savagery against the swords and bravery of the heroes of the Hyborian Age.
Drawn from the pages of Robert E. Howard’s Conan stories, this roster also includes creatures and alien horrors from H.P. Lovecraft ’s Cthulhu Mythos, to which Howard inextricably bound his Hyborian Age. Other entries are original, chosen carefully to refl ect the tone and dangers of Conan’s world.
